DNI

This page covers the duplex-network (DNI) configuration of the WorkCentre 3345 and the one cartridge it runs on: the 106R03624 black toner cartridge, an extra-high-capacity unit good for about 15,000 pages before it needs replacing. A configuration-specific page exists so that buyers of this exact variant land on the right shelf the first time — and the supply itself is reassuringly simple, a single black cartridge stocked below as a single and in packs of two, three, five and ten.

The DNI variant changes the printer, not the cartridge. Duplex printing and network sharing define how the 3345 DNI is used — two-sided workgroup documents arriving from every desk — while the cartridge it consumes is the same one fitted across this model family. That is good news for whoever stocks the supply cabinet: one code to remember, one cartridge type on the shelf, and a long rated yield that keeps reorder moments rare even on a shared machine.

Toner Cartridges for the WorkCentre 3345 DNI

Which cartridge should you buy?

With a single cartridge design, the only real choice is pack size. A lone 3345 DNI in a small office is well served by the single 106R03624 plus a spare kept sealed; the cartridge's 15,000-page rating means replacements are infrequent, and an unopened spare removes the shipping wait when one finally runs out. Offices running several of these machines, or feeding a central supply room, will find the 5 and 10 packs cut both ordering effort and cost per cartridge. Judge by monthly volume: the heavier and steadier it is, the larger the pack that pays off.

Chip, toner and everyday use

Pull the sealing strip from a new cartridge completely before fitting it, and let a cartridge that has been stored somewhere cold warm to room temperature first — condensation is no friend to toner. The printer reads the fitted cartridge's chip to track remaining toner, so a gauge that drops in steps rather than smoothly is normal behavior. Near the end of a cartridge, pages may fade toward the edges; a gentle side-to-side rock levels what toner remains. Keep the spent cartridge for recycling rather than binning it with general waste.

Frequently Asked Questions

What toner does the WorkCentre 3345 DNI use?

The Xerox 106R03624 black cartridge — one cartridge only, rated at about 15,000 pages at 5% coverage. If the code on your order matches the code here, the cartridge is the right one for this model.

Is the cartridge the same as the WorkCentre 3335 DNI takes?

Yes. The WorkCentre 3335 DNI and this 3345 DNI configuration share the 106R03624, as does the Phaser 3330 line, so a single stock of cartridges can cover all of them.

How do I install a fresh cartridge?

Open the printer's front access area, slide the spent cartridge out, unseal the new one and rock it gently to loosen the toner, then slide it in until it clicks and close the cover. The machine registers the new supply automatically.

Does duplex printing change how long the cartridge lasts?

Duplexing saves paper, not toner — each printed side uses the same toner as a single-sided page. What changes cartridge life is how much of each page is covered in text or graphics, which is why yields are quoted at a standard 5% coverage.
